REO&I UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 I
SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO PCN-241, REQUEST TO DELETE NUCLEAR SAFETY GROUP REVIEW RESPONSIBILITIES SOUTHERN CALIFORNIA EDISON COMPANY SAN DIEGO GAS AND ELECTRIC COMPANY THE CITY OF RIVERSIDE, CALIFORNIA THE CITY OF ANAHEIM, CALIFORNIA SAN ONOFRE NUCLEAR GENERATING STATION, UNITS 2 AND 3 DOCKET NOS. 50-361 AND 50-362
1.0 INTRODUCTION
By letter dated August 11, 1988, Southern California Edison Company (SCE) or the licensee requested a change to the Technical Specifications for Facility Operating License Nos. NPF-10 and NPF-15 that authorize operation of San Onofre Nuclear Generating Station (SONGS), Units 2 and 3 in San Diego County, California.
2.0 EVALUATION The proposed change would delete both TS Section 6.5.3.4.a, which requires the Nuclear Safety Group (NSG) to review the safety evaluations for (1) changes to procedures required by Specification 6.8, equipment, or systems and (2) tests or experiments completed under 10 CFR 50.59; and TS Section 6.5.3.4.g, which requires the NSG to review events requiring 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> written notification to the Commission. The licensee based this request upon the extensive technical and managerial review which these items receive by station personnel. The NSG review is considered by the licensee to be redundant and to divert resources from other functions of the NSG.
The function of the NSG, as stated in the Technical Specifications, is to provide an independent review and audit of designated activities in specific functional areas. Both the Standard Technical Specifications for Combustion Engineering Pressurized Water Reactors (NUREG-0212) and American National Standard ANS-3.2/ANSI 18.7-1976, which was endorsed by Reg Guide 8812160100 88: 1209 PIDR ADOCK 05000361

-2 1.33, call for review of activities described in TS 6.5.3.4.a and 6.5.3.4.g to be performed independent of the plant staff. At San Onofre this review is performed by the NSG. The staff considers these to be essential func tions which cannot be eliminated. The purpose of the NSG review described in Section 6.5.3.4.a is to verify that the changes, tests, or experiments did not involve a change in the Technical Specifications or an unreviewed safety question as defined in 10 CFR 50.59(a)(2). The purpose of the re view described in Section 6.5.3.4.g is to prevent or reduce the probability of recurrence. For both purposes it is important that the review be per formed by a group separate from the plant to ensure objectivity and inde pendence. Therefore, the justification that these issues receive extensive technical and managerial review by station personnel is not acceptable.
Because the licensee's proposed amendment provides no means of performing these important functions, the request for license amendment is denied.
